Abstract
A HID luminaire includes a HID lamp, a reflector, and a lens. The reflector has a proximal end, a distal area, and an intermediate are positioned therebetween. The reflector has an interior surface that includes a first portion that extends from the proximal end to the intermediate area and a second portion that extends from the intermediate area to the distal end. The second portion is less light reflective than the first portion. The lens has two different diffusion rates and includes a center portion having a lens inner diameter and an outer portion surrounding the center portion. The lens inner diameter is about the same diameter as the diameter of the intermediate area. The outer portion is more diffuse than the center portion but allows light to be transmitted therethrough.
